Conflict between trajectories and density description: the statistical source of disagreement
Paolo Allegrini, Paolo Grigolini, Luigi Palatella +1
We study an idealized version of intermittent process leading the fluctuations of a stochastic dichotomous variable . It consists of an overdamped and symmetric potential well w…
Real event detection and the treatment of congestive heart failure: an e fficient technique to help cardiologists to make crucial decisions
P. Allegrini, R. Balocchi, S. Chillemi +5
Using a method of entropic analysis of time series we establish the correlation between heartbeat long-range memory and mortality risk in patients with congestive heart failure.
Short- and Long-Term Statistical Properties of Heartbeat Time-Series in Healthy and Pathological Subjects
Paolo Allegrini, Rita Balocchi, Santi Chillemi +3
We analize heartbeat time-series corresponding to several groups of individuals (healthy, heart transplanted, with congestive heart failure (CHF), after myocardial infarction (MI),…
Statistical analysis of air and sea temperature anomalies
Nicola Scafetta, Tim Imholt, Paolo Grigolini +1
This paper presents a global air and sea temperature anomalies analysis based upon a combination of the wavelet multiresolution analysis and the scaling analysis methods of a time…
Non-extensive diffusion entropy analysis: non-stationarity in teen birth phenomena
N. Scafetta, P. Grigolini, P. Hamilton +1
A complex process is often a balance between non-stationary and stationary components. We show how the non-extensive Tsallis q-entropy indicator may be interpreted as a measure of…
Entropic Analysis of non-Stationary Sequences
M. Virgilio, P. Grigolini
The aim of this paper is to shed light on the analysis of non-stationary time series by means of the method of diffusion entropy. For this purpose, we first study the case when inf…
